^ Yeah, I had several I had to delete because of the limit in options.

There's
Frozen Fever, and also their funeral dresses in the first film (seen at the end of "Do You Want to Build a Snowman?" when they're back to back against the door). I also just realized that I forgot Anna's white formal dress from the beginning of
Frozen 2.
Yeah, I love most of them, too, which made it hard to trim the list.
1. Elsa (White "Show Yourself" Dress)
2. Anna (Green Coronation Dress from the first film)
3. Elsa (Winter Dress from Olaf's Frozen Adventure)
4. Elsa ("Let It Go" Dress)
5. Anna (Queen Dress)
6. Elsa (Blue Dresscoat and Boots from II)
7. Anna (White Formal Dress from II)
8. Anna (Black & Purple Dress from II)
9. Anna (Magenta and Blue traveling clothes from the first film)
10. Elsa's Nightgown
